The CEO of James M. Singleton Charter School and Dryades YMCA is resigning after Louisiana's Department of Education voided standardized tests for 165 students due to suspected cheating and irregularities, according to a report from The Lens.

Gregory Phillips told the news website he plans to step down after the leadership transition is complete. His departure comes after the state last summer learned that students received copies of LEAP tests beforehand. Test administrators were also coaching students, and the staff took LEAP tests themselves as well.

Education Department spokeswoman Sydni Dunn said Friday the department has not yet confirmed the tip the department received regarding the school sharing tests ahead of time with students and test administrators coached students. She stressed that officials learned many students received help on LEAP tests without authorization by their Individualized Education Program.

The Lens reported earlier this week that four educators at Singleton Charter were fired last week for the testing scandal. The firings come months after the Orleans Parish School Board voted Nov. 16 to close the Mahalia Jackson Elementary School in Central City and turn it over to Dryades YMCA.
